Between 15,000 and 18,000 years ago, a series of momentous floods crashed through the Pacific Northwest, reaching heights of up to 400 feet where Portland lies today and carving the landscape of
the Columbia Gorge and Willamette Valley.

Geologist and gifted speaker Scott Burns will focus on the incredible story of J Harlen Bretz’s discovery of the Ice Age floods and the pioneering research that Bretz used to prove his discovery to
the world. Burns will also discuss the floods’ effect on the formation of 16,000 square miles of Pacific Northwest terrain, from eastern Washington to Astoria and the Willamette Valley.
